The history of Celtic began when the Romans, lovers of thermal waters, venerated the saving virtues of the waters of Niederbronn-les-Bains by using them for bathing and hygienic purposes. But long before the Romans recognized these beneficial waters, the bust of a Celtic goddess, symbol of fertility, was already erected near the source. The Celts were then present in a large part of Europe and were known for their rites of worship of nature, especially around the theme of water, symbol of eternal life and place of purification.
